Hi there!
Evaluating f(x) at x = 9 means we must use the piecewise function where x = 9 is included.
f(x) = 12 includes 9 because a "≤" is inclusive of the interval. Thus:
f(9) = 12
Answer:
1.35 pounds each
Step-by-step explanation:
16.2 divided by 12 equals 1.35
v^ 3 = 1000
so v = cube root of 1000
v = 10
i think N=32
